3. 3 MIPI European Transparency Project (ETP) Introduction The EU Council agreed the 3rd package of EU energy market legal obligations (ref 715/2009) on 3rd September 2009. These obligations are passed to the UK government and detail the requirements on EU gas transporters for the transparency and publication of specified data. Transparency projects are aimed at delivering improved and consistent publication of transmission data amongst EU members in order to facilitate the requirements of market participants, and to act as a step towards a regional (and ultimately a single European) energy market. The EU 3rd package grants an 18 month implementation window for EU member states. The compliance deadline is 3rd March 2011 to which National Grid must adhere, however, we will implement early on 15th November 2010. This legislation aims to facilitate an EU-wide gas market by provision of a common dataset.

4. 4 MIPI European Transparency Project (ETP) Background - Market Information Provision Initiative (MIPI) In 2007 was the first phase of MIPI Its remit was to move the delivery of the key obligated and Incentivised Market Information (behind approximately 50% of the reports in the legacy IE3 system) to a new application sited on the strategic, high availability Gas Market Reporting System (“GMRS”) infrastructure. In 2008/09 was the 2nd and final phase of MIPI Further Market Information was transferred onto GMRS, including all of the remaining information that was still published by IE3 after the completion of the MIPI Phase 1 project and which would continue to be required. Additionally, MIPI Phase 2 made provision for the continued publication of obligated shipper specific data which had been sourced from IE3, thus allowing IE3 to be decommissioned. Note: As part of MIPI Phase 2 a link was provided from the IE3 page to allow those people who had this listed as a “favourite” link easy access to MIPI (so the link did not disappear after IE3 was decommissioned). This will be disabled as part of the European Transparency project.

5. 5 MIPI European Transparency Project (ETP) Summary of changes (MIPI ETP) ENTSOG Publish obligated data to the ENTSOG (GTE) platform (automated service). Link to ENTSOG: www.gas-roads.euwww.gas-roads.eu MIPI The MIPI ETP project will build on the current strategic MIPI platform for data consistency and transparency across TSO’s:- Link to MIPI: www.nationalgrid.com/uk/Gas/Data  Standardisation of Units of Measure.  Additional data to be published (both increased volume & frequency).  Upgrade of graphics package - provision of new graphs and enhancement to existing graphs.  Extend the online retrieval availability of MIPI data to a rolling five years of history (data to be available with effect from 01/10/2010 and to be built up over time).

8. 8 Data to be supplied to the ENTSOG platform DataFrequency NominationsDaily (D-1) Re-nominations (including final nominations) Publishing Hourly Data (within day) Allocations Monthly (M+7 for Exit and M+16 for Entry). Scaleback of interruptible capacity Adhoc (D+1) - Information will be displayed when interruption occurs, for example, no data will be issued unless interruption of capacity (scaleback) occurs. Capacity and Tariff dataMonthly and Adhoc Note 1: Capacity and Tariff data is currently provided by a manual process. This data will become part of an automated service. Note 2: Normal Units of Measure (UOM) will be issued to ENTSOG. Unit conversion information is provided on slide 16. MIPI European Transparency Project (ETP)

9. 9 The following data items will be submitted to ENTSOG:- Nominations 1 daily value for the ASEP's (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). This value is the initial aggregated nomination value (aggregated input nominations & output nominations across all shippers at each ASEP (Entry) and Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). This will be issued to ENTSOG once it is available. Re-nominations/final nominations Hourly value for the ASEP's (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). This value is the final end-of-day aggregated nomination (which could be a re-nomination) value. Aggregated input nominations or re-nominations & output nominations or re-nominations across all shippers at each ASEP (Entry) and Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). This will be issued to ENTSOG once it is available, before the end of D+1. Data to be supplied to the ENTSOG platform - further detail (for new items)

10. 10 MIPI European Transparency Project (ETP) The following data items will be submitted to ENTSOG:- Allocations Values for ASEP's (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). The initial allocation value for each ASEP and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL) will be issued to ENTSOG once it is available. This is the original ‘provisional’ value for each ASEP (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). The ‘confirmed’ allocation value for each ASEP (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL) will be issued to ENTSOG once it is available (M+7 for Exit and M+16 for Entry). Values are the aggregated allocation values (aggregated input allocations & output allocations across all shippers at each ASEP and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). Data to be supplied to the ENTSOG platform - further detail (for new items)

11. 11 MIPI European Transparency Project (ETP) Data to be supplied to the ENTSOG platform - further detail (for new items) The following data items will be submitted to ENTSOG:- Scaleback of interruptible capacity An indicator showing whether any scaleback of interruptible capacity has occurred on the day. Interruption in this instance refers to capacity shortfall resulting in scaleback. Scaleback (Interruption) Detail One set of information for each instance of interruption at the ASEP's (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). For each instance of interruption the date and scaled back (interruption) amount at the appropriate ASEP (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL ) in kWh/day will be provided. For each day of scaleback interruption the total booked interruptible capacity at the appropriate ASEP (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL) and the scaled back amount as a percentage of the whole booked Interruptible amount at the ASEP (Entry) and the Interconnector (Exit) Points (Moffat, Bacton IUK and Bacton BBL). The information will be issued to ENTSOG by D+1, where D is the day of Interruption. Note: This is interruption resulting from scaleback - entry capacity. This is not interruption due to shortage of supply.

12. 12 MIPI European Transparency Project (ETP) Data to be supplied to the ENTSOG platform - further detail (for new items) The following data items will be submitted to ENTSOG:- Capacity and Tariff data Capacity and Tariff data is currently provided by a manual process and is already viewed on the ENTSOG platform:- www.gas-roads.eu As part of MIPI ETP this data will become part of an automated service. The data itself will not change.

13. 13 MIPI European Transparency Project (ETP) Data to be supplied to the ENTSOG platform - further detail (for new items) Sample of screens to be populated (including automated capacity and tariff data). Note: Data is for illustration purposes only, using data extract from other service providers

A footnote will be added at the footer of the Prevailing View, Report Explorer and at the footer of all relevant reports to act as a reminder that conversion information is available in the “Help” menu of Prevailing View. Conversion Factors National Grid publishes data in UK standard units. To convert to other units, please refer to the following conversion factors:- 1) kWh (25oC, 0oC, 1.01325 bar) = 1 kWh (15oC, 15oC, 1.01325 bar) x 0.9990 2) Normal mcm volume = Standard mscm (UK) x 0.9479 3) mscm to kWh = mscm * 1000000*CV (39.6)/3.6 4) kWh to mscm = kWh/1000000/CV (39.6)*3.6 The above formulas are to be used as a guide only.
